Description

WATER DESALINATION AND TREATMENT PROCESS, THROUGH AN ADVANCED INVERSE OSMOSIS PROCESS, MAKING USE OF A HYBRID FEED SYSTEM AND OTHER ALTERNATE ENERGIES.

TECHNICAL FIELD The present invention has its technical field in the field of energy, biotechnology and product design sustainable eco innovative and efficient process of misalignment and water treatment, through an advanced reverse osmosis process, making use of a hybrid power system and other energies alternate The product is developed in the field of energy, biotechnology and sustainable eco product design BACKGROUND For years, the desalination of seawater or brackish water has been the solution for many countries that have scarce water resources. The technology of desalination is highly energy intensive and its cost is high for developing countries that do not have fossil fuels. Defined sustainability from meeting the needs of the present without harming the needs of future generations, is that it is necessary that the desalination of seawater, which needs energy for its realization, becomes independent as much as possible, fossil fuels. The fact of using the latter efficiently is not enough to obtain sustainability, which is why it is essential to develop desalination processes that use alternative sources of energy.

The main objective of the invention is the development of research lines that generate benefits for both the company and the community, through the development of new sustainable processes and products for the generation of alternative energies, as well as water remediation and water applications. byproducts, among others. That is why at present it considers of vital importance the incursion in the national problematic of the shortage of water. The invention also includes the incorporation and training of highly qualified personnel and seeks to promote the potential of inclusion with the development of suppliers composed of small and medium-sized Mexican engineering companies to support the scaling and validation at the industrial level of the prototypes to be developed, as well as its first plans of innovations with electrical and electronic systems for remote monitoring of plants to be used in hotels, communities, industry, ships, exploration, drilling, production and processing platforms, their appropriate design, prototype construction, testing and validation with the incorporation of new membrane materials for the evaluation of the technical feasibility of the project, using new sustainable technological infrastructure for the assimilation of technologies, knowledge transfer mechanisms generated and facilitator schemes of learning and adoption Practices that ensure optimal animalization and adaptation in multiple sectors, using mainly alternative energies within their maritime facilities and thereby support this industry.

Wind energy, solar thermal, photovoltaic and geothermal energy are currently used in desalination processes. Desalination systems powered by renewable energy are divided into two categories; the first that includes the distillation processes by means of heat generation and the second category includes membranes and distillation processes powered by electrical or mechanical energy produced by renewable energies.

From the last census carried out in the country, it was determined that there are 147 desalination plants that use conventional energy, of which 94% are based on reverse osmosis technology but unfortunately 31% of them were out of operation and have very high operating costs. .

EXISTING TECHNOLOGIES Within the applications of alternative energies combined with desalination units, the photovoltaic cells represent the best alternative given that both the demand for fresh water and the price of the land on which they settle are low. For larger demands it is necessary to resort to conventional distillation plants coupled to a solar thermal system known as indirect solar desalination; the distillation methods used in this are the multi-stage distillation and the multi-effect distillation.

Recent advances in the investigation of processes at low temperature have resulted in an increase in the capacity of the desalination as well as a reduction in the energy consumption of the multi-stage plants, thus ensuring a long-term operation with exceptional stability conditions. The formation of scale and the corrosion of the sea have been reduced; with the disadvantage that both turn out to be expensive.

On the other hand we have the processes based on the use of membranes: reverse osmosis and electrodialysis; it is predicted that these processes, in particular those of reverse osmosis can take advantage in the market of thermal desalination. Both processes require energy inputs to assimilate the existing osmotic pressure between fresh and salt water.

Likewise, reverse osmosis and electrodialysis are mature and commercially viable technologies for their adaptation in a system based on Solar Panels as a valid option to be implemented in remote sites. Being exclusive, it turns out that the most proven system has been PV-reverse osmosis to minimize the use of fossil fuels.

This product is the result of an arduous applied research and technological development within the framework of sustainable projects that the country requires and thus support the productive capacity and the generation of competitive advantages. It was developed with the purpose of obtaining tangible and intangible results that contribute to increase the competitiveness of the company at a national and international level in the field of sustainability, specifically in terms of quality water and renewable energies that are friendly to the environment and their conservation and that minimize dependence on the use of fossil fuels.

To increase the added value of the project, a hybrid system composed of photovoltaic solar cells and a vertical turbine has been implemented, which together lead to the generation of the energy necessary for the operation of the desalination plant in question. It also requires the inclusion of an array of water batteries, specially designed to support the operation of the submersible pump for the supply of seawater to the system as well as auxiliary use of biodiesel as fuel.

DETAILED DESCRIPTION OF THE INVENTION Development and industrial application process unique in its type of seawater treatment and desalination, through a modular type plant with advanced reverse osmosis technology and with low energy consumption. The operation of the system is powered by 220v or solar energy using very efficient photovoltaic panels, wind energy generated by air turbines and a motor with a biodiesel energy recovery system as backup system and support in the operation of the control process. variations of salinity and temperature. Incorporating a water battery of the ASYL type specially designed to stably support the operation of the submersible seawater supply pump to the system. The water purification system consists of one or more containers or mobile equipment placed side by side. A container houses the reverse osmosis filtration platform, along with the support of batteries that store solar energy, constituting an energy backup that ensures the supply of clean and potable water uninterruptedly. The purified water is stored in a storage tank in the second container, next to the control system of the solar panel. The series of high efficiency photovoltaic panels are installed on a structure of galvanized steel and easy assembly that covers the container and are supported by four steel posts in the four corners. These panels provide the necessary energy to operate the system. The complete system is a solution ready to work with all the elements and components integrated and supplied. As an option, a bottling line powered by solar energy or operating independently can also be added to the equipment.

Once the untreated water, either from the sea or from brackish sources, is pumped into the system, the pump and the compressor powered by solar energy or at 220v start working. First, a self-cleaning in the MULTIMEDIA FILTER system (B) before going through the (OI) process to the system, eliminating all solid particles suspended in the water and waste; then the filtration of the membranes (H) removes all the remaining solid particles, the turbidity, the viruses and bacteria and most of the organic compounds.

Based on the membrane technology developed by the system, it propels the water through a series of circular membrane plates in two separate streams, in such a way that effectively minimizes the pressure of the pumps and membranes. It thus requires less energy than any other system, allowing the unit to operate using only solar energy.

After the process of Advanced Reverse Osmosis, after treatments, and UV Rays, the water that could have an input higher than 10 thousand PPM becomes fully potable water below 300 PPM. The smallest of the equipment can obtain 100 liters a day of drinking water, and the largest one up to more than 1 million liters of drinking water per day.

The system is divided into 2 phases: 1) input / load and 2) advanced reverse osmosis treatment Phase 1: entry and loading Solar, wind and water power unit: It presents a hybrid system that integrates solar panels (300W X square meter) and a vertical recycled polyester turbine that generate 70 W at a wind speed of 15m / s.

As a support system, it has an aquatic battery arrangement with a power generation of 24 W.

Seawater collection unit: This unit owes its operation to submersible solar pumps that transport water from the sea to the pre-treatment unit. These are powered by a system of water batteries designed for that purpose and that need 24 W.

Components and phase 2.

Phase 2: advanced reverse osmosis treatment a) chlorine dosing system A water injection meter, which controls the different elements of water supply to the RO system (Reverse Osmosis). The measuring pump allows controlling different functions, such as the percentage of input and output. The same chlorine dosing system adds the necessary amount of chlorine to the water feeder, thus protecting the biofouling system. b) multi media and activated carbon filter: Pre-treatment unit: The treatment will be carried out through the use of a multimedia filter and a PVC storage system, cartridge-type sediment filters of 5 - 20 microns that stops most of the suspended solids in the water, with an automatic backwashing system, which also protects the high-pressure pump carried by the RO system. These filters offer the highest performance rates without the need for continuous maintenance. This is achieved by loading in the tank, first the larger granules of low density in the upper part, with at least one layer of high density granules below. The large granules remove the large suspended particles, leaving small particles that seep into the lower part. The same tank is divided into three stages of filtration, and stops all matter such as sand and sediments (turbid) up to 20 microns. Automatically retro wash the system when necessary. The filters measure 9"x 48", with a tank of a high-performance fiberglass composite. c) start and absorption pump: Feed the RO system at 40 - 50 psi, based on the required water flow. It is a SHURflo type stainless steel diaphragm pump. d) military pressure pump: The pressure pump for military use type WEG, models Super Duplex stainless steel, zero maintenance, which works on small scale models at 900 psi. In large-scale models, pumps with higher pressure are designed, including a centrifugal pump, a turbine with energy recovery, and frequency meter, making the equipment one of the most efficient and silent that exist. e) dosing system for sodium bisulfite, acidity and ph: An injection measurement system controls different elements in the water of the RO system in the equipment. The measuring pump allows controlling different functions. The Sodium Metabisulfite Dosing system neutralizes chlorine, which is added to the feedwater to greatly reduce bacteria. The waste serves as an excellent biocide. It controls the level of acidity and prevents ruptures in the membranes, equalizing the pH of the water. f) uv-ray sterilization system: By going through this process, it sterilizes the water, alternating the DNA structure inside the bacteria. g) post treatment of ozone system By going through this process, it sterilizes the water, burning the outer membranes of the bacteria. h) accommodation membranes Corrosion resistant, fiberglass components, work at 1,000 psi. i) proteo membranes: With a Dow Fiimtec membrane, for the best treatment of salt water fluids, with Thin Film Composite membranes. j) motor: It works in single phase, or three phase. k) pipes resistant to high pressures of stainless steel.
