The NHG grid type wastewater decontamination machine is designed for large-scale intake structures, a variety of pumping stations, and water inlets of wastewater treatment plants as it separates residue and ensures subsequent water equipment is able to operate normally.
The grid type wastewater decontamination machine is installed obliquely within sewage pipes, and forms a dip angle on the ground. The rake bars and machine rack are fixed together to separate the residue from the water with these rake bars. The wastewater decontamination machine is equipped with chain guides on both sides, there are multiple rake bars between the transmission chains for residue separating, and the rake teeth deeply penetrate into the screen bar spacing to remove the residue via the transmission chains. The grid type wastewater decontamination machine consists of grid transmission unit, machine rack, residue rakes, skimmer and electrical control unit.Parameters of the grid type wastewater decontamination machine

Features of the grid type wastewater decontamination machine
(1) High automation: The operation methods include manual control, inching control and automatic timing control.
(2) Operating flexibly: The user can adjust the interval according to their needs and complete the periodic operation.
(3) Since the grid type wastewater decontamination machine has an automatic cleaning device, the machine will not be blocked during operation and it does not require significant maintenance.
(4) The rake teeth are made of stainless steel or nylon for excellent corrosion resistance.
The grid type wastewater decontamination machine uses different kinds of materials and it can be customized according to customer requirements, such as civil engineering ditch width, ditch depth, and spacing between the teeth of the rakes.
The groove depth of the grid type wastewater decontamination machine is customized by the customer according to their needs in practical application. The groove depth of the machine is usually no less than 0.5m and no more than 15m.
