Title - Stage cleaner for rainwater.

Scope of production.

The stage cleaner will be used to purify rainwater for storage tanks, (see Fig. 2.) Thus, visible impurities will not run to the tank.

The stage cleaner is intended as a cleaning supplement for private households. The rainwater can be used as a partial replacement for groundwater. In this connection it will be: Toilet flush, washing machine, car wash etc. See fig. 7 + 8 + 9th

Shaping ♦

The stage cleaner is a three-layered three-piece cleaning vessel with a flow connection between the divided vessels.

Cleaning.

Purification takes place in three stages (three zones). In the first and partial second zones the water will be purified. In the second zone, the water is finer purified through a foam rubber filter.

Extra cleaning.

In the case of an exceptionally large number of floating units in the first zone, a float block with pipe connection to an overflow pipe can remove these. Additional fine cleaning can also be done in the third cleaning zone with two methods - as shown in FIG. 16 + 17.

Equipment in cleaning vessels.

A water damping mat (turbulence - stop) is placed in the first zone. In the second zone, a foam rubber module is centered on a square tube with holes in the foam rubber area. The mentioned filters are for fine cleaning before the third clearing / cleaning zone.

Cleaning and maintenance.

The foam gum stars in the second zone are layered.They are thus easy to replace and clean.Either by tying, rinsing in water or in washing machine.

Emptying of impurities.

At the bottom of the three Shared Vessels are three separate drain pipes for removing bottom sludge. The bottom of the lamb is separated by two partitions. Thus, the sludge can be continuously removed separately.

Overlobsror.

Due to the connected vessels, the water will stand just as high in the three clean-season zones.

Thus, overflow rudders are advantageously placed just above normal water level in the first zone.

Page 3 PRIOR ART

Except for one exception, rainwater storage tanks are used to a very limited extent in private households. On the basis of seals, the following systems are used: 1. Poserens.

2. Sand cleaner.

3. Biological cleansing.

The rainwater separator (patented).

This cleaning unit works best with water collection from roofs of 2 under 25 m. However, you will risk that impurities will not be maintained if the rainfall becomes too large. The filter must be cleaned after 2oo - 5oo liters of rainwater, and since most houses will able to collect over 60000 liters per years, this purification unit has not gained any widespread use.

Bag's.

As a home-made unit, this system has been most widely used. The water here runs into a bag with a mesh width of approx. o, 5 - 1 mm. The water ambulance in the bag will act as a mill and comminute major impurities. The result is a continuous clogging of the bag. In this cleaning system there is no overflow pipe.

Sand's.

On a trial basis for detached houses.

Biological cleansing.

On a trial basis for detached houses.

Page 4 THE TECHNICAL PROBLEM TO BE SOLVED.

The existing cleaning units available do not fulfill the intended functions. Suitable cleaning methods must meet various minimum requirements, as the following points will clarify.

Item A. Cleaning quality.

The rainwater must be cleaned to such an extent that visible impurities do not flow to the storage tank.

Point B. Overflow.

There must be an overflow pipe so that uncleaned rainwater cannot flow to the storage tank at filter stops or extraordinary amounts of rain.

Item C. Volume.

The size of the cleaning unit must by nature be relatively small, as one cannot expect that detached houses etc. has high ceiling heights or extra space available.

Item D. Location of cleaning module.

Cleaning unit must be positioned so that there is an opportunity to clean the same.D.v.s. as low as possible i.f.t. storage tanks.

Item E. Cleaning / maintenance.

Cleaning and disassembly of filter units should be carried out effortlessly a few times a year. The cleaning process must be able to be viewed and evaluated without any major technical insight.

Item F. Cleaning capacity.

Cleaning module must be dimensioned so that the capacity is 2 intended for ordinary detached houses up to 15o m.

Assessment of known and lesser-known cleaning units will be compared in Scheme 1 with reference to the minimum requirements outlined here (points A-F).

Page 6 THE NEW TECHNOLOGY.

The rainwater stage cleaner is new by a combination of known techniques.

A purge unit for storage tanks with water intake in the vessel sides. The generation is equipped with separate zoned drain pipes for sludge emptying.

It is characterized by an open, horizontal, three-part flow-through vessel.

As an intermediate cleaning unit, a star-shaped, layered foam rubber filter is mounted on a centered square tube with flow holes in the foam rubber area.

TECHNICAL EFFECT.

Embryo development.

When purifying with the stage cleaner, various impurities will be retained, so that the nutrient content of the stored tank water will be greatly reduced - in order to avoid germ development.

(Process drive for germ development: light + heat + nutrition.) Water turbulence.

The FIG. lo (2) the water turbulence mat shown will distribute / dampen so that throughout the width of the vessel, it will flow smoothly through holes in the partition between the cleaning zone 1 and 2. When the water has reached the second cleaning zone, it will hit the bowl holding the star-shaped purification modules. This results in a further water turbulence stop. The large area of the foam will also act as a turbulence stop for the water.

Clarification Zones ♦

Due to the turbulence stop device, calm zones will form in the water, so that impurities will be distributed at the top and bottom. 15. This will cause the foam module located in the 2nd cleaning zone to be heavily relieved for major impurities.

Volume of stage cleaner. Page 7

Compared to other known and lesser-known storage tanks for storage tanks, the stage cleaner relative to the exterior dimensions will have a large cleaning capacity, which is due to the following factors: 1. A water flowing horizontal structure that allows a cleaning effect before foam rubber filter - due to clearance zones.

2. A star-shaped foam filter which, due to its design, has a relatively large cleaning area.

Location of stage cleaner.

Due to the water intake / water outlet in the sides, the production need not necessarily be placed above the storage tank. The unit will be able to be placed at a low height relative to the storage tank.

Location of foam rubber felt.

As seen in FIG. 2A (16) and FIG. 13 (16), the foam sheets are located in the middle of floating / settling impurities.

Referring to FIG. 15 (21-22).

Alternative application of cleaning felt.

Rounded up in FIG. 14A, it is possible to use the entire cleaning unit in other containers.

Foam rubber fastening.

The layered felt is centered by square tubing. The modules can be fastened by means of the end bowl and two brass bars with threads at the free ends. The fastening ice with wing nuts is made in the second partition. 14 and FIG. 14 A regarding design / fastening. See fig. 11 for holes for brass rods and holes for square pipes.

Expansion of foam rubber area.

The construction with layered foam modules of 3 cm thickness means that the cleaning area can be continuously expanded.This will involve a longer pipe and longer fastening rods.

GB 96 00013 U3 page 8 ADDITIONAL CLEANING OF RAINWATER.

Pre-cleaning ♦ In the first cleaning zone is mounted a float block with plastic hose connection for overflow pipes. By adjusting the length of the plastic hose, the angle of the block in the water will change and thereby determine how close to the surface impurities must be removed. lo (1 + 8).

1. Finishing method.

Absorption of finer impurities in the third cleaning zone will be carried out with loose hanging curtains, which hang loosely in the vessels on top of the rowed tubs. See fig. 12 (24) and FIG. 16 (24 + 25). The preferred material choice is fine mesh nylon / foam rubber.

2. Finishing method.

In the third cleaning zone is placed a wire basket with a sealing edge on three sides. The preferred cleaning material in the wire basket will be quartz sand of over 1.55 mm grain size. See fig. 17 (26 + 27).

TECHNICAL EFFECT.

In the upcoming sizing table there will be a set up where previous explanations will be supported.

Foam - cleaning area.

The design is based on the layered module as shown in FIG.

14 and 14 A. The cleaning area is also based on a cleaning of the felt 3-4 times a year depending on the roof area. The table assumes a model where the diameter is 3 cm (from tip to tip of the star).

Average Detached house.

The water pollution rate is based on an average.

Volume of stage cleaner.

This one is stated in 1iter, based on exterior dimensions.

Weight of stage cleaner.

Weight in kg. will be numerically less than the liter, since the water does not usually reach the edge.

Page 11 EXECUTION EXAMPLES.

In FIG. 2 can be seen where the stage cleaner is used in a rainwater collection system. In FIG. lO (6) the water enters from roofs. The water will then fashion the turbulence mat located in Fig. 10 (2). The water will then run into the second cleaning zone through inflow holes in partition (4). Next, in FIG. 14 and 14A, the foam filters shown will be passed. Then the water will flow through holes in square tubes (8) and outside the rudder.

The water will continue through the hole in the vessel side (11). The further flow of water out of the 3rd zone will take place through the one in fig. 12 (13) The female sleeve is shown. Finally, the water will pass through a connecting pipe between the female sleeve and the storage tank.

Furthermore, in FIG. 10 (1) shown a overflow mirror where extraordinary quantities of water could pass out to the sewer.
