Disc filters, screen filters, sand filters and backwash systems applied in agriculture, greenhouses, landscaping and industrial water treatment.
Application Fields
Disc, screen and sand media filters are widely used in field drip irrigation, greenhouses, orchards and fertigation, municipal greening and landscaping, livestock water supply, and industrial circulating water treatment. Requirements for filtration rating, flow rate and backwash method differ considerably between these applications, so selection must consider both water source quality and irrigation method.
Long-term project practice has given us experience with many working conditions, from sand removal for well water and algae removal for river water through to pre-treatment of high-turbidity water. We can combine filters with control valves and fertilizer equipment into a complete filtration system suited to site conditions.
Typical Conditions and Selection Approach
Sandy well water or river water: use a hydrocyclone desilter for primary sand removal, then a sand media or disc filter for fine filtration.
Drip irrigation anti-clogging: disc filters are the first choice, with element rating selected between 120 and 200 mesh according to water quality.
Greenhouses and small estates: screen or disc filters with manual backwash, compact and easy to maintain.
Large agricultural estates: fully automatic backwash disc or sand media filtration systems to reduce manual attendance.
Fertigation: add a venturi injector or jet agitator after filtration to feed water and fertilizer together.
Municipal and landscaping irrigation: combine hydraulic control valves and air valves to keep network pressure stable and venting reliable.
Project Delivery Process
Step 1 Requirement confirmation: flow rate, source water quality, connection size, control mode and application.
Step 2 Selection and quotation: recommended model combination, configuration list and quotation.
Step 3 Production and inspection: scheduling to order, with pressure testing and function testing before shipment.
Step 4 Shipment: customs documents and transport arranged under the agreed trade terms.
Step 5 Installation and commissioning: installation instructions and remote technical guidance.
Project Support We Offer
In the early stage of a project we can assist with filter selection and system connection advice, and provide product drawings and 3D models where needed so they can be integrated into your overall pipe network design.
During project execution we can support customer or third-party inspection and provide test records on request. After delivery we continue to supply wear parts and spares to help the equipment run reliably over the long term.
Parameters to Confirm Before Selection
Maximum sand content and turbidity of the source water, and whether algae or sediment peaks occur seasonally.
Design system flow rate and allowable pressure loss, which determine filter size and the number of units in parallel.
Backwash water source and discharge conditions, which decide whether manual, semi-automatic or fully automatic backwash is appropriate.
On-site power supply and the desired level of automation, which affect control valve and electrical configuration.
Installation space and civil works conditions, which affect how the filtration skid is laid out.
