Fully Automatic Chemical Dosing and Water Treatment System – Made in China

Company Overview

We specialize in the design and manufacture of advanced water and wastewater treatment equipment. Our core business covers:

• Petrochemical industry water treatment

• Municipal water supply and purification

• Urban and industrial sewage treatment

• Domestic sewage treatment systems

• Pure water and reverse osmosis (RO) equipment

• Waste gas and pollution treatment solutions

Working Principle

Our fully automatic dosing system is pre-assembled and tested at our facility to ensure plug-and-play operation. Upon delivery, users simply:

1. Install the system in the dosing room.

2. Connect the metering pump outlet to the dosing pipeline.

3. Link the chemical tank inlet/outlet and water supply pipe.

4. Provide power and connect sensor signals (e.g., pH, conductivity) to the control cabinet.

This streamlined process reduces on-site installation time, minimizes errors, and ensures quick commissioning, guaranteeing project timelines and operational reliability.

Key Features

• Three-Tank Integrated Design – Enables continuous chemical preparation and dosing with minimal operator intervention.

• Dual Feeding System – Supports both dry powder and liquid polymer for flexible chemical selection.

• PLC-Based Automation – Fully automatic operation reduces labor costs and improves accuracy.

• Precision Dosing Options – Equipped with a screw pump or metering pump (default: screw pump) for adjustable and consistent chemical delivery.

• Compact & Easy Maintenance – Base-free design with a sleek structure for simple upkeep and long-term reliability.

Technical Parameters

System Structure

The system uses a jet mixer to disperse chemicals or powders via high-speed water flow, enhancing dissolution efficiency and fineness. The three-tank overflow design ensures continuous preparation, maturation, and dosing. By leveraging gravity and solubility differences, the system automatically separates dissolved and undissolved substances. A low-speed agitator further optimizes solution uniformity for consistent performance.

Applications

• Wastewater treatment plants

• Industrial water recycling systems

• Municipal water purification

• Petrochemical and chemical processing

• Effluent treatment and pollution control

Advantages:
Pre-assembled and pre-tested for fast deployment
Fully automated operation with PLC control
High dosing accuracy and flexible chemical options
Low maintenance and compact design

Packing and Delivery

1. Waterproof packing with the international export standard by 20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and Power Cabinet will be packed in Wooden Case or Iron Box. Other Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will use Waterproof cloth to pack all of them. The motor, gear box or other easily damaged parts, we will put them into box. We have a professional shipping department, they will try their best to save your container quantity.
