Chemical Dosing System for Water Treatment

In water and wastewater treatment, inconsistent or inaccurate chemical dosing leads to poor effluent quality, regulatory violations, and wasted operational costs. Our fully automatic chemical dosing system for water treatment delivers precise, intelligent, and low-maintenance feed of coagulants (PAC), flocculants (PAM), pH adjusters (acid/alkali), disinfectants (sodium hypochlorite), antiscalants, and more-ensuring optimal process performance across municipal, industrial, food & beverage, power, and aquaculture applications.

* Multi-Chemical Capability: Single skid supports 1–6 chemicals (e.g., PAC + PAM + NaOH + HCl) with independent control loops.
* ±1% Dosing Accuracy: Flow-proportional or ORP/pH/turbidity-based feedback ensures exact dosage-no overuse, no under-dosing.
* Smart Automation: PLC & touchscreen HMI with data logging, alarm alerts, and optional cloud/IoT remote monitoring.
* Corrosion-Resistant Design: Tanks, pipes, and pumps in PP, PVC, PVDF, SS316L-built for aggressive chemicals like chlorine, acid, and caustic soda.
* Compact & Modular: Skid-mounted for fast installation; scalable from small plants to 50,000 m³/day facilities.
* Global Compliance: CE certified, ISO 9001 manufactured, and compliant with EPA, EU BREF, and local discharge standards.

Our system automates the entire chemical management workflow-from storage to injection:
* Chemical Storage: Bulk tanks or day tanks for liquid chemicals; sealed hoppers for dry powders (e.g., PAM, lime).
* Solution Preparation (if needed): Automatic dilution and mixing for concentrated chemicals (e.g., 10% NaOCl → 0.5% working solution).
* Precision Dosing: Diaphragm, peristaltic, or progressive cavity pumps deliver chemicals based on real-time signals (flow meter, pH probe, ORP sensor).
* Process Integration: Seamless connection to upstream/downstream units like DAF, clarifiers, RO systems, or sludge dewatering machines.
* Monitoring & Control: All parameters logged; SMS/email alerts for low chemical, pump failure, or out-of-range conditions.

Our automatic dosing devices are engineered for a wide range of water treatment chemicals:
* Coagulants: PAC (Polyaluminum Chloride), Alum, Ferric Chloride
* Flocculants: PAM (Anionic, Cationic, Non-ionic)
* PH Adjusters: Sulfuric Acid (H₂SO₄), Hydrochloric Acid (HCl), Sodium Hydroxide (NaOH), Lime
* Disinfectants: Sodium Hypochlorite (NaOCl), Chlorine Dioxide (ClO₂)
* Antiscalants & Corrosion Inhibitors: For RO pretreatment and cooling towers
* Defoamers & Nutrients: For biological treatment processes

Q1: Can one system dose both acid and caustic soda safely?
A: Yes. We use chemically isolated circuits with compatible materials (e.g., PP for acid, PVDF for caustic) and physical separation to prevent cross-contamination or reactions.

Q2: Do you provide chemical compatibility guidance?
A: Absolutely. Our engineers will review your chemical SDS (Safety Data Sheets) and recommend the right wetted materials, pump types, and safety features (e.g., leak trays, ventilation).

Q3: Is remote monitoring really useful?
A: Operators using our IoT-enabled systems report 40% fewer site visits and faster response to issues. You can check tank levels, dosing rates, and alarm history from anywhere-via phone or computer.
