Abstract

A tank/septic tank (A) with source sorting/separation of solid and liquid masses from water closets, household water, which are passed in pipe (H) to tank (A). A rotatable device at the top of the tank, consisting of a ring (D) with wheels (C) which travel on a recess (B) in the opening of the tank (A), has one or more partitions (E). On each side of the partition there is located/suspended a perforated container or a woven bag (F), which separates solid and liquid masses; all the liquid flows on and is collected in the tank below. When a bag/container (F) is sufficiently full, the ring (D) is rotated in such a manner that the pipe (H) begins to fill a new bag/container (F), while the filled bag will hang on the other side of the partition (E) and 'dry'/reduce in weight by approximately 80% until it is time for removal and rotate the ring (D) with the partition (E), thus permitting a new bag/container to begin to be filled. The liquid masses are then treated in known purification plants or used in known underground watering and fertilizing systems. For seldom used holiday homes the liquid material is evaporated, by being raised into a channel (L) with an upwardly rising air current.

Description

A Toilet Separator Device
The invention comprises a tank/septic tank system wherein all the contents of toilets and household water in houses and cabins are passed out in pipes and into a collecting tank. There are very strict rules for the further transport and treatment of such waste. In towns and densely built-up areas the contents are passed in pipes to public purification plants, where they receive further treatment before being released into lakes/rivers. For sparsely built-up areas it is expensive to have long pipelines and in this case buried tanks have been employed which have then been collected by large waste disposal tankers and driven to public purification plants.
This is an extremely expensive system for the users and the municipal refuse disposal service. Moreover the state of the art purification systems are very expensive and encumbered with a great many weaknesses. Most purification plants are incapable of separating amongst other things many nutrient salts, which have great value as fertilizers. When these are released into rivers/lakes and the sea, they cause substantial pollution and damage.
The object of the invention is to provide a separation system which separates solid and liquid substances as they are introduced at the top of the tank, preferably for buried tanks in houses or cabins, or for terraced houses/maisonettes. This object is achieved by means of a device which is characterized by the features in the claims presented.
The invention is based on a separator system with perforated containers or preferably woven bags which are suspended on a revolvable device/ring at the top of the opening of a tank. On the ring there is attached a central plate and on each side of this there are then suspended, for example, woven bags, which contain solids, but allow the liquid to pass through and this is then collected in the tank below.
Two bags are located and held open on each side of a partition in the middle of a rotatable device suspended at the top of the tank. When one bag is full, the device is rotated approximately a half turn. The filled bag is then left to dry while the other is filled up.
The size of the bag is suitable for 2-3 months' use by a family of 3-4 persons. When a bag is filled up after 3 months, the bag which has been left to dry has reduced in weight by approximately 80%. It is easy to remove, and a new bag is fitted and the rotatable device is rotated a half turn and the new bag which has been fitted begins to be filled.
The dried bag with its contents which are easy to handle is brought to a reception point where the contents are heated up in, e.g., a tunnel furnace for sterilization and then ground down to become a valuable soil improvement medium. An evaporation device can be provided at the bottom of the tank in order to greatly reduce the liquid part at the bottom of the tank. An overflow pipe then passes the remains of the liquid part into a storage tank for subsequent use for agricultural purposes, fertilizing and watering.
For use in holiday homes which are only used for short periods of the year, the liquid part will be able to be completely evaporated. Inspection once a year should be sufficient. The filled bag is placed in a clean plastic bag, sealed and brought to a reception point for sterilization and grinding to granulate.
Tests have shown that, e.g., from a household of four members, the solids in a dried state will only amount to approximately 2 kg per person per month.
If the bag is replaced every quarter, it will weigh approximately 20 kg and will be easy to handle. It is therefore recommended that a municipal or private inspection body performs 4 collections per annum on payment of a fee which can be low and inspection every quarter provides a guarantee that the system works and does not cause pollution.
The invention is especially intended for sparsely built-up areas and holiday homes, outside or on the outskirts of urban areas where long connecting pipelines have to be laid, if the contents are to be conveyed to existing central purification plants.
The purification plants in their existing form are known for releasing very large amounts of nitrogen and nutrient salts into rivers, water and lakes. It will cost several hundred millions of crowns to alter the existing purification plants in order to reduce the discharges to an acceptable level. It is estimated that to continue the laying of pipes out to outlying areas will be very expensive. The number of buildings which at present are not connected to a purification plant is estimated to be approximately 1/3 of all Norwegian households, approximately 500,000. In addition to this there are a large number, approximately 300,000, holiday homes at the seaside and in the mountains, which at present have unsatisfactory sanitary installations. With the use of the water closet separator all the nitrogen and nutrient salts are taken care of, thereby preventing these from being carried out into rivers, water and lakes and causing pollution.
The fertilizer value of the discharge from present systems in Norway is estimated to have an annual value of approximately NOK 200 million according to current fertilizer prices.
This resource, which constitutes the separated liquid part from the toilet separator, can, by means of a newly-developed underground watering system, be fully utilized for ecological production of food plants.
The toilet separator is based on the recycling of water when this is desirable. The evaporation can be disconnected, and it can give substantial savings in water consumption. This can give lower water charges in places where access to water is limited. The liquid part of fertilizer water used for garden watering will offer the opportunity for increasing food production on an ecological basis.
People who have lived for generations in urban districts and are used to water closets are reluctant to forgo the convenience which these offer.
Many types of so-called biotoilets based on composting/mouldering of faecal matter and urine have been developed, and all of them are dependent on the user carefully complying with the prescribed directions for use if a satisfactory result is to be achieved.
If the directions are not complied with, this can result in considerable pollution. None of these can compare with water closets with regard to comfort.
Given a good economy, further development work will be possible in order to adapt the system to include maisonettes in towns and densely built-up areas. When the liquid masses are to be used for agriculture, this will require the building of considerable storage capacity in countries with frost during the winter. With present day technology for the manufacture of rotation moulded plastic tanks, these can be produced at very low prices. The tanks are manufactured in recyclable plastic materials in sizes up to 12,000 litres. The purchase costs for storage tanks will be offset in the course of a few years by the use of the fertilizer value in the liquid masses. The invention with the above-described source sorting and evaporation system can be implemented in many different ways, and in the attached sectional drawing of the upper part of a tank/septic tank an embodiment is illustrated where A illustrates the tank. B illustrates a recess in the opening of the tank. C illustrates wheels which support a circumferential ring D. In the middle of the ring there is attached a dividing plate E. Opposite this there are suspended on each side preferably woven bags F on securing devices/hooks G. The pipe H passes everything from toilets/households into bags F and when one is sufficiently full, the suspension ring D is rotated a half turn and a new bag is attached to the hooks G. The filled bag F is hung to dry while the other is filled.
J illustrates a small compressor fan which passes air/gas out from the tank into an underground system of perforated pipes K. The compressor fan can be electrically operated where there is access to electricity, or operated by a small wind propeller.
L illustrates a pipe, arranged for a rising air current. Inside it are devices M paternoster belts wicks which raise liquids from the bottom of the tank A up to the air current in the pipe L, where the moisture is evaporated. As a power unit for the belts wicks a small wind propeller N can be used, or where electric current is available, a small electric motor.
