A common problem in wastewater treatment and management is the accumulation of sludge generated in the same.
As a solution ESTRUAGUA offers its sludge storage hopper, model TAF ®, Capacities ranging from 5m3 to 100 m3.

This type of sludge storage tanks are manufactured in cylindrical form with standard character, demand can be built in a trapezoidal shape.

The standard construction material is carbon steel A/42-b quality, however demand can be built into any other material.

Description:

Support Legs:

Normally manufactured hot rolled IPE or UPN depending on the load capacity of the hopper, each team has four legs which are electrically welded plates of either union or the body of the hopper.

Body:

Cylindrical run at the top and tapered at the bottom, its thickness varies between 4.00 mm and 6.00 mm depending on the volume of the same external reinforcements standard profiles, either angular or UPN.

At the top of the tank located the mouth load of sludge, the deposit is completely closed thereby preventing unwanted odors and has a safety rail across the borders.

Stairs:

The hoppers “”TAF ®“” Have two types of ladders, the first that comes to the discharge and the second takes us from the discharge to the top of the tank or cargo area.

Spout:

Axctuador execution by electric or hydraulic piston through the intermediary of hydraulic, both run / Off.

Surface protection

All storage bins “”TAF ®“” Made in A/-42.b quality carbon steel, are subjected to the following process to finish and corrosion protection

- Interior
- Sand blasting to the degree of
- 4 layers of tar epoxy primer (50 microns each)

The auger screen Tvt-020 is a combined team for the separation of the solids present in wastewater and the subsequent compaction and dehydration of the same. The solid material in suspension in the transport fluid is deposited on the screen clogged, which causes an increase in level at the front of it and a decrease in the back. At that time begins to run the propeller, which cleans the screen, turn up the material, dehydrated and compact.

The team consists of the following parts:

- Sieve filter.
- Augers.
- Compactor.

The screen filter is formed by a screen with light passing between 0.25 and 10mm which retains the suspended solids in the liquid transport. This screen is kept clean thanks to the corresponding brush set on the outside of the helix.

The screen can be of two types:

- Strainer Johnson profile between 0.25 and 2mm.
- Perforated sheet strainer or triangle between 3 and 10mm diameter holes.

The auger consists of a propeller shaft that can lift without solids deposited. Without shaft auger to extract materials of varying shape and size, which are otherwise difficult to transport.

The compactor: transport helix itself serves to make the compaction-dehydration of screening, resulting in a reduction in the volume even higher than 50%.

YOUR BENEFITS:

1 .- Fully automatic, with the possibility of varying the rotation speed as needed.
2 .- Output hopper screened solids, length depending on application.
3 .- System of compaction, which prevents clogs the grate and facilitates water runoff.
4 .- The tilting system allows us to examine the state of both the grid filter, and the helical thread at any time.
5 .- This area is simply threaded screened solids transport, which are aimed at the head of compaction, the thread is to be with the soul of the tube.
6 .- Grid filter, possible execution profile Johnson, perforated or triangular in steps of 0.25mm to 10mm.
7 .- helical spiral with special design which incorporates a brush wear, this is what makes the screening of solids.

(NOTE: As an option we can introduce a cleaning system on the grid filter)

Pollution of surface water resources, by combining water drainage systems, and partly also of storm water tanks, consists of all solids, which are present in the wastewater. This includes a very wide range of dissolved semi-dissolved, fiber and solids with different structures and specific weights (plastic strips, sanitary napkins, diapers, condoms, feces, paper, etc..).

Increased restoration of natural surface water resources to its natural state, makes it essential to avoid the discharge of floating material in the future.

The construction of walls submerged outfall structures, only avoids spills of floating matter, because substantial fluid velocities, tend to intensify with the short space that usually exists between the submerged walls, these rates tend to increase the discharge of solid material.

Watershed-tank continuous, can play their role only to a limited extent, because of the large volumes of water and greatly increase the proportion of light materials.

Detention basins and retention channels have the disadvantage that the combined untreated water is poured into the river course, once they are full.

A combination of tank or tank-sieve gate spillway, is the best way to meet the criteria in these cases. In this concept, retention of highly contaminated flow is the main task of the tanks. On the other hand, the grid eliminates light substances, floating solids, which contaminate the area.

Design Features

ESTRUAGUA TAH-01 ® Spillway sieve, are designed in a modular system. All types consist largely of elements which can be put together to get the most suitable type of spillway screen for each particular application. The robust rack holding the screen, cleaning the rail stack of combs and hydraulic or pneumatic cylinder.
The spillway gate of the screen is built to pre-stress bars narrow sieve. The cross-section of the small bar ensures optimal use of screen area, low resistance and high capacity screen flow.
The standard range is 4 mm bar, and all unwanted floating material are retained.
One or more lanes are arranged in cleaning the drain depending on the elongated screen. These guides travel on the screen surface.
The stack of dies which are mounted on the rail fits into the cleaning of the screen grid, supporting and guiding the bars of the grate of the screen. The stack of combs thus replaces the rigid transverse elements which are undesirable in water cleaning system.
Cleaning the screen is turned on and off depending on the level.
The mechanism is usually hydraulic.
