Compact Precise Durable Reliable

The QWDS Polymer dosing system delivers precise, automated chemical powder dosing for wastewater processes—reducing manual handling, ensuring consistent coagulation/flocculation and enabling DCS integration for real‑time control. Its compact skid design, stainless‑steel frame and modular pump options (screw or diaphragm), plus standard safety fittings (back‑pressure and safety valves, filters, diaphragm gauges) and export carton packing, ensure robust quality, easy installation and secure transport. Available in multiple capacities with 220V power, a one‑year warranty and 3–20 day lead times, the system supports online sensors and automatic pump switching to keep treatment stable, compliant and low‑maintenance.

Here are six four-word subtitle options (each emphasizes a different perspective):

The QWDS Polymer dosing system is a 220V, skid-mounted automatic chemical powder dosing unit engineered for wastewater applications such as regulation, coagulation and sludge dewatering, offered in modular pump configurations (2–6 sets) with 1000–2000 L/h capacities and compact footprints for rapid installation. It automates precise addition of PAC, PAM, acids, alkalis, carbon sources and other reagents with online monitoring of pH, residual chlorine, DO, suspended solids and sludge concentration, plus automatic pump switching and DCS integration to match dosage to flow and process concentration. Built with selectable imported screw or diaphragm metering pumps, safety components (back-pressure and safety valves, filters, diaphragm gauges, cleaning pipelines) and programmable electronic control, the system enhances dosing accuracy and operational safety, reduces manual intervention, and is supplied with a one-year warranty.

220V Automatic Powder Doser

The QWDS Polymer dosing system is a China-made automatic chemical powder dosing skid (220V, 1-year warranty) designed for wastewater treatment tasks such as regulation, coagulation and sludge dewatering. It automatically meters PAC, PAM, acids/alkalis, carbon source, nutrients and demulsifiers using imported screw or diaphragm metering pumps and includes standard safety and maintenance features like back-pressure and safety valves, filters, diaphragm pressure gauges and cleaning pipelines. Capable of online monitoring (pH, residual chlorine, DO, suspended solids, sludge concentration), automatic pump switching and DCS integration, it offers multiple model options to match different flow rates and process requirements.

Accurate, Reliable, Efficient, Durable

Born from years of industrial metering expertise, the QWDS Polymer dosing system was engineered as a compact, skid-mounted Auto Chemical Powder Dosing Skid with 220V power and a 1yr warranty, reflecting the brand’s focus on reliable, service-oriented manufacturing. It delivers precision gravimetric and volumetric dosing, PLC and flowmeter integration, automatic batching, sealed powder handling and anti-caking feed to maintain consistent polymer concentration while minimizing dust and product loss. Key advantages include high dosing accuracy, reduced chemical waste, easy installation and maintenance, corrosion-resistant materials, modular components and optional remote monitoring, making the QWDS Polymer dosing system a cost-effective, user-friendly choice for water treatment and industrial dosing.

Material introduction

The QWDS Polymer dosing system features a corrosion-resistant stainless steel skid and chemical-resistant tanks and piping (PVC/HDPE or PTFE-lined) engineered to handle acids, alkalis, PAC, PAM and other dosing agents. Metering components use imported-brand screw or diaphragm pumps with reinforced polymer or stainless wetted parts, together with back-pressure and safety valves, filters and diaphragm pressure gauges made from chemically compatible materials. All wetted components and cleaning pipelines are selected for longevity and chemical compatibility to ensure safe, automatic dosing and reliable integration with onsite DCS and sludge dewatering processes.

FAQ

What kinds of applications is the Auto Chemical Powder Dosing Skid (220V, 1 yr warranty) best suited for?

The skid is designed for automated, accurate dosing of powdered chemicals in liquid treatment and process systems. Typical applications include municipal and industrial wastewater treatment (coagulants, flocculants), cooling tower and boiler water treatment (anticorrosion, antiscalant), paper and pulp processing, mining and mineral processing (reagents), and other batch or continuous chemical feed processes where dry powders must be metered into water or process streams.

How do I install and power the dosing skid on a 220V site?

The unit is built for a 220V AC mains supply—confirm whether your site is single-phase or three-phase and the local frequency (50/60 Hz) before installation. Mount the skid on a level, solid foundation and anchor it to prevent vibration. Provide a dedicated, properly rated circuit with a suitably sized breaker and a reliable earth/ground connection. Allow access for hopper loading, maintenance and ventilation. If integrating with building controls, follow the factory wiring diagram and have a qualified electrician make the final connections.

How do I determine if my powder is compatible and how accurate will dosing be?

Compatibility depends on powder properties (bulk density, particle size, flowability, hygroscopicity and solubility). The skid typically uses a controlled feeder (screw, vibrating tray or loss-in-weight system) and can achieve repeatable dosing within the manufacturer’s specified tolerance—verify the model’s accuracy range before purchase. We recommend sending a sample powder for factory testing or performing an on-site trial to confirm feedability and expected dosing accuracy. For hygroscopic or agglomerating powders, use dry storage, dust-tight hoppers and optional agitation or de-agglomeration options.

What safety and environmental controls do I need to use with powdered chemical dosing?

Use appropriate PPE (gloves, eye protection, masks or respirators as needed) when loading powders. Keep hoppers closed or use bag-in/bag-out feeding systems to minimize dust. Install local exhaust ventilation or dust collectors if powders generate airborne dust. For combustible powders, follow relevant ATEX/NFPA guidelines and use ignition control measures. Ensure spill containment under the skid and have MSDS for all chemicals on site. Regularly inspect seals, couplings and dust control components to prevent leaks.

What routine maintenance and calibration are required to keep the dosing skid reliable?

Regular tasks include: checking and cleaning the hopper and feed path to prevent bridging or caking; verifying and tightening mechanical fasteners; lubricating bearings and gearboxes per the manual; replacing wear parts (screw flights, liners, seals) on the recommended schedule; and inspecting dust filtration and seals. Calibrate feeders periodically using a known mass over a set time to verify dosing rate and adjust controller settings. Frequency depends on usage; daily visual checks and monthly function tests are typical for continuous systems.

If I experience inconsistent dosing or clogging, what troubleshooting steps should I take?

First, check the powder condition—moisture uptake or lumps are the most common causes of clogging. Ensure hopper agitation or de-aeration devices are functioning and the powder is within storage specs. Inspect the feeder for blockages, worn flights, faulty motors or speed-controller faults. Confirm control signals (PLC, 4–20 mA) and power supply are stable. Clean or replace clogged filters and check for foreign objects. If problems persist, record operating parameters (feeder speed, power, ambient conditions) and contact the supplier with photos and data for targeted support.
