Description

Trustworthy Fluid Control for use in Wastewater Treatment Plants

-          Optional electrical actuated penstocks

-          Durable and heavy duty sluice gates

-          Effective flow control and constriction.

Principle and Function:

The Wamechsi Group’s Sluice Gates and Penstocks act as a flow slop or volumetric flow control. The gate is raised in order to open the channel or increase the flow of water through the channel.  In order to stop or decrease the flow of the water through the channel the gate is lowered.  This is a crucial element, since it enables maintenance to take place in selected areas in the plant without shutting down the entire waste water treatment plant. 

The gate can be lowered with a motorized system, or it can be lowered and raised by hand with the help of a gear system. The gates are mounted at the inlet works of the plant and determines how much water will be supplied to the screens and thus the rest of the plant. It is advised to be skilled in the safe use of the plant and in the maintenance which needs to be carried out by taking into account both the technical and safety rules.

Wamechsi offers the following selection of Sluice Gates:

Wall Mounted Gates

These types of gates are normally used to open or close an opening in a wall. These gates can close off a square or round hole in a concrete wall with the seal around the complete periphery of the opening. These gates are normally used in the following applications:

-          Division boxes.

-          Reactor walls.

-          Chlorine by-pass channels.

Channel Gates

These types of gates are normally used in channels to isolate or bypass the flow as required in the inlet works of a wastewater treatment plant and are screw operated, with a hand wheel or a gearbox mounted on a beam which forms part of the channel gate.

 

 

 

Weir Gates

These gates are normally used as flow control gates, whereby the over the top of the gate is controlled by adjusting the height of the gate. These gates are normally used in the following applications:

-          Adjustable overflow weir in biological reactors.

-          V-notch weirs for flow control at axial flow pumps.

-          V-notch weirs at final effluent.

Flow Dividers

These types of gates are normally used for diverting flow into either of two channels between two plants, normally an old plant adjacent to a newly built plant.

Flap Gates

These types of gates are normally used as non-return gates, allowing flow in one direction only at axial flow pumps or sludge recycle pumps.

Telescopic Bell Mouths

These types of gates are normally used as fluid control draw off valves for sludge or scum withdrawal at settling tanks.

Telescopic Bell Mouths

These types of gates are normally used as fluid control draw off valves for sludge or scum withdrawal at settling tanks.

Dewatering Gates

These gates are normally adjustable double sided sliding gates for sludge drying beds or dams.

T-Key Operation Design

The T-Key type of operating gear or spindle arrangements are operated by a hand wheel which can be removed when level setting or specific isolation is required. It’s also used where a pedestal and spindle arrangement is in the way of the movement or center of a platform. The T-Key design is normally used in the following applications:

-          Setting of specified flow.

-          Isolation of flow during maintenance work.

-          Used as anti-tampering operating gear.

The Wamechsi Group’s Sluice Gates consists of the following key parts:

-          Sluice Gate

The sluice door acts as buffer in order to block limit the amount of water flowing through the channel.  The gate is manufactured from stainless steel for durability.  The gate is designed to withstand the pressure due to the water pressing on the gate.

-          Frame

The frame secures the sluice door in place.  The frame is mounted to the side of the channel in multiple locations in order to ensure that the pressure from the water does not dislocate the frame from the mounted position in the wall.  The frame is manufactured from stainless steel for durability.  It is designed to withstand the pressure from the water acting against the door and in turn the sluice frame.

-          Penstocks

The Penstocks are the stainless steel shaft responsible for pulling and pushing the sluice gate into place for operation. The penstocks are controlled by the manual hand wheel which rotates around the penstock along threads causing the penstock to pull or push the sluice gate

The Wamechsi Group’s Sluice Gates typically operates as follow:

The incoming wastewater enters into inlet works which are divided into different channels by a division box. The control of each flow can only be achieved by the installation of sluice gates into channels and division boxes. The sluice gates are operated by a manual hand wheel or electrical actuator which are used to turn and operated the penstocks. The penstocks typically pull or push the sluice gate in the frame work, installed in the channel, open or close.
