Sand washing plant water recycling system design 65 tph
Why water recycling is essential for UAE sand producers
Water is one of the most precious resources in the United Arab Emirates. With annual rainfall averaging less than 100 mm in many regions and a growing population driving demand for both construction materials and freshwater, water conservation is a national priority. For sand washing plant operators, the challenge is particularly acute—conventional washing circuits can consume up to 150–200 cubic metres of fresh water per hour for a 65 tonnes per hour operation. Discharging this water without treatment is not only environmentally irresponsible but also increasingly restricted by UAE regulations. A well-designed water recycling system reduces fresh water intake by 80–95%, significantly lowering operating costs and ensuring compliance with environmental standards. The Sand washing plant water recycling system design 65 tph is therefore a strategic investment that delivers both financial and environmental returns. OCP Mechanical Company, with over 40 years of direct manufacturing experience, offers custom-designed recycling systems integrated with our washing plants, all at factory-direct prices.
System components and flow configuration
A complete water recycling system for a 65 tph sand washing plant typically includes several key components. The first stage is a settling pond or a hydrocyclone cluster that separates coarse solids from the process water. The overflow—water containing fine particles—then flows to a thickener, where flocculants are added to accelerate sedimentation. The clarified water from the thickener overflows into a clear water tank, ready for re-use in the washing circuit. The underflow from the thickener, a slurry of fine solids, is typically sent to a filter press or a centrifuge for dewatering, producing a filter cake that can be disposed of or sold as a by-product. OCP's system designs include a PLC-based control panel that monitors water levels, flow rates, and flocculant dosing, automating the process for consistent performance. The Sand washing plant water recycling system design 65 tph must be matched to the specific characteristics of the feed material—clay content, particle size distribution, and settling rates—to ensure efficient operation.
Sizing the system for 65 tph operation
Accurate sizing is essential for the Sand washing plant water recycling system design 65 tph to achieve the desired water recovery rate. A 65 tph sand washing plant typically generates approximately 80–120 m³/h of process water containing suspended solids, depending on the feed's fines content. The settling pond or thickener must be sized to provide sufficient retention time for particles to settle. For a thickener, OCP recommends a diameter of 6–8 metres with a sidewall depth of 3–4 metres for this capacity. The flocculant dosing system should be capable of adding 5–15 grams per tonne of solids processed, with adjustable dosing to accommodate variations in feed. The filter press should have a plate area of 30–50 m² to handle the solids load, producing filter cakes with 20–25% moisture content. All sizing calculations are based on typical UAE aggregate characteristics; actual values depend on feed analysis, which OCP provides free of charge as part of our design service.

Water balance and operational efficiency
A well-designed system achieves a water balance where fresh water is only needed to make up for losses due to evaporation and moisture retained in the final product. For a 65 tph sand washing plant with a closed-loop recycling system, fresh water consumption can be reduced to 5–15 m³/h—savings of 80–90% compared with a once-through system. This reduction directly lowers water purchase costs and eliminates discharge fees. The Sand washing plant water recycling system design 65 tph also reduces the load on settling ponds, minimising dredging frequency and the associated costs. OCP's system includes sensors that monitor turbidity and pH, ensuring that the recycled water quality remains suitable for washing. Operators can expect a payback period of 12–24 months for the recycling system investment, depending on local water tariffs and disposal costs. All financial data are for reference; actual savings depend on site-specific water costs and utilisation rates.
Integration with existing washing equipment
For many UAE operators, the Sand washing plant water recycling system design 65 tph involves integrating the recycling system with an existing washing plant. OCP offers modular designs that can be retrofitted to most sand screw washers, log washers, and hydrocyclone circuits. The integration typically involves installing a sump pump to transfer process water to the thickener, and piping to return clarified water to the washing plant's feed tank. Our engineering team conducts a site survey to determine the optimal layout, minimising pipe runs and pumping head. We also provide a comprehensive installation manual and remote supervision during commissioning. For greenfield projects, OCP recommends designing the entire plant—washing and recycling—as an integrated system, achieving the best efficiency and lowest overall cost. All retrofitting recommendations are for reference; actual installation requirements depend on site layout and existing equipment.
