Abstract

A filter bag used to remove suspended debris and solids from water being transferred via a pump or gravity means. The filter bag can be used in the civil engineering and construction industry. Preferably the filter bag can be placed inside a water settlement tank to enhance solids removal. The filter bag may be made from polypropylene with an elastic nylon collar located at one end. Preferably the filter bag has holes of 250, 100 or 50 microns. Advantageously use of the filter bag reduces pollution to water courses and sewers.

Description

DESCRIPTION Title
Dirtbag
Background
The Dirtbag relates to a permeable filtration bag which traps solids in water that is being pumped from one place to another during civil engineering and construction works.
In the Construction & Civil Engineering industry, water is often pumped out of excavations or trenches to another location to allow the relevant works to commence.
Whilst pumping the water from the excavation, solids (i.e. stones, sand, and rubble) are also transported within the water and moved to wherever the pump outlet is located. This can cause significant pollution to water courses, sewers and the environment in general.
Statement of invention
To overcome this problem the Dirtbag has been invented to catch and remove solids that are travelling within the water during the pumping process before the water ends up in its new location.
Advantages The Dirtbag in its' raw form can be simply laid on the ground with the pump outlet hose entering the collar of the Dirtbag meaning that all the water is pumped through the Dirtbag which would trap all the solids. (Refer to drawing number 3) Also the Dirtbag can be placed inside a water settlement tank which will trap the solids inside the tank. This enhances the effectiveness of the water settlement tank dramatically which itself is designed to trap solids within water. (Refer to Drawing number 4) However, due to the design of a settlement tank and the fact that it has water constantly being pumped through it, the tank doesn't effectively trap all solids passing through it.
Once the Dirtbag is full with debris and solids it is simply disposed of and a new Dirtbag is attached to the outlet hose or inside the settlement tank.
The Dirtbag can be of any shape or size to Suit the pumping equipment and the environment into which it is being used.
Introduction to the Drawings Note:
For the purposes of these drawings and associated descriptions, the term dirty water' is used to describe water that contains silt, debris and solids. The term clean water' is used to describe water that has had silt, debris and solids removed.
Drawing number 1 of 4: This drawing shows the Dirtbag in its simple form. The Dirtbag which is made from 100% polypropylene is an envelope style with an elastic nylon collar located centrally at one end. The Dirtbag can be any size dependant on the size of pump and the volumes of water passing through it. Figure 1 shows the Dirtbag in its form prior to use. Figure 2 shows how the bag will fill up with solids during the pumping process. The holes in the membrane of the Dirtbag can be 250, 100 or 50 microns depending on the size and amount of solids that are needed to be removed from the water.
Drawing number 2 of 4: This drawing shows the Dirtbag in its cubic form. There is no difference whatsoever in performance or how it works but is simply an option and these shaped bags will fit better inside a settlement tank.
Drawing number 3 of 4: This drawing shows the Dirtbag in use in its simplest form.
Figure 1 is showing an excavated trench with the pumps inlet hose pumping out the water which at this stage includes the solids.
Figure 2 is simply the pump being used to transfer the water from one place to another.
Figure 3 is showing the dirty' water exiting the outlet hose and into the Dirtbag, the solids being removed from the water and the clean' water leaving the bag.
Drawing number 4 of 4: This drawing shows an example of how a Dirtbag can be used inside a water settlement tank. The settlement tank itself is designed to trap solids that sink to the bottom of the tank whilst dirty water is pumped through it. However, due to the volumes, speed and lack of settlement time, the settlement tank does not catch all solids.
Figure 1 is showing the dirty water entering the settlement tank.
Figure 2 shows the dirty water immediately passing through the Dirtbag.
Figure 3 shows the Dirtbag trapping the solids and allowing clean water to permeate through its membrane into the settlement tank.
Figure 4 shows clean water passing through and exiting the tank.

Claims (5)

  1. CLAIMSI. A filter bag used in the civil engineering and construction industry that will catch and remove suspended debris and solids from water being transferred via a pump or gravity means.
  2. 2. The filter bag can be used inside a water settlement tank to increase the effectiveness of the tank.
  3. 3. The process greatly reduces pollution to water courses and sewers by catching debris and solids whilst the water is being passed through the permeable membrane of the bag. tcAmendments to the claims have been filed as follows I. A filtration bag constructed from water permeable material for use when suspended solids must be removed from water before entering a water system or watercourse, said water can be delivered into the filtration bag by means of pumping or gravity.2. A filtration bag according to claim I that has means to facilitate lifting and transportation.3. A filtration bag according to any preceding claim that has means to secure the outlet hose from a water delivery system within, or to, the filtration bag by means of a collar.
  4. 4. A filtration bag according to any preceding claim that has means to secure the outlet hose from a water delivery system within, or to, the filtration bag by means of an elasticised collar.
  5. 5. A filtration bag according to any preceding claim that is constructed from a biodegradable material. * .* * ** * ** Sd S **. SSS S * S. * SS
