Polymer preparation Unit Advantage

• Avoid the need for manual operations – Prevent dosing errors, operation stops.
• Standardization of the obtained polymer – Concentration, maturation time, homogeneity.
• High efficiency mixers – Provide a low flow mixing for a homogeneous flocculant polymerisation without mechanical deterioration.
• Optimised process – Visual access to the process and alarms, fieldbus distributed control (optional) provides informative and easy to access equipment and status application updates, controlled costs. Intelligent system that feeds the process when needed, regulated by an ultrasonic level switch.
• Reliability and Robustness in Any Environment.

Material: Stainless Steel, PP, or FRP

Material	Pros	Cons	Best For
SS304	Stands up to corrosion, strong, lasts a long time	Higher cost	Most projects
SS316	Even better corrosion resistance	Costs more than 304	High salt, very corrosive conditions
PP (Polypropylene)	Cheap, handles chemicals well	Low strength, ages faster	Small, low requirement projects
FRP (Fiberglass)	Handles chemicals, lightweight	Expensive, hard to fix	Chemical plants, special conditions

Bottom line: If your budget allows, pick stainless steel. Pay once and use it for 15 years. You will not have to think about it again.

I have seen too many plants buy a PP tank to save money. Three years later, the tank is cracked and leaking. The fittings are brittle. They end up buying a stainless steel unit anyway. The cheap one ends up being the expensive one.

Feeding Screw: What Matters

The feeding screw is one of the parts that gives people the most trouble. Pay attention to three things:

• Material: Must be stainless steel. Carbon steel will rust within months. Rust gets into your polymer solution and ends up in your sludge cake.
• Anti caking: The screw end should have heating to stop powder from caking up from moisture. Without heating, the powder can harden right at the discharge point. The screw turns but nothing comes out.

• VFD control: Adjustable screw speed lets you match changing polymer demand. When your sludge flow drops, the screw slows down. When it picks up, the screw speeds up. You do not waste polymer.

3.4 Control System: The Brain of the Unit

A good unit should have PLC control with a touchscreen. Look for these features:

• Automatic water fill, powder feed, and mixing
• Concentration control (feed rate and water flow work together)
• Low level alarm (warns you before the storage tank runs dry)
• Fault alarms (feeder jam, water supply failure, and so on)

• Remote communication ready (so you can hook it up to your SCADA system)

Without good controls, you are back to babysitting the unit. An operator has to check it every hour. They have to adjust the feed rate when the sludge changes. With a good control system, the unit runs itself. The operator checks it once a shift and moves on to other work.

Polymer preparation Unit Feature

• Fully automated operation — saves labor costs and prevents dosing errors, operation stops
• Standardization of the resulting polymer — concentration, maturation time, homogeneity
• High efficiency mixer — Provides low flow mixing for homogeneous flocculant polymerization without mechanical degradation
• Optimized process — visual access to process and alarms, can feed the process when needed, regulated by ultrasonic level switches
• Compact design — easy to transport and relocate
• Safe and reliable — operation with airlift and overflow protection

Polymer preparation Unit Remark

♦ Model selection: Process capacity or flow volume is necessary
♦ Raw material: SS304 or SS316.
♦ Manufacturer: We have our own workshop so that best quality and loweat price can be provided for you.
♦ Customization: Custom-made is available.

What Makes DAGYEE Units Different

• Triple tank continuous design: Prep, aging, and storage tanks are separate. That gives you 45 to 60 minutes of aging time. No shortcuts.
• Material options: SS304, SS316, PP, or FRP depending on your conditions. We help you pick the right one for your wastewater.
• Anti caking feeding: Heated screw end, tapered hopper with smooth walls. No bridging, no caking, no surprises.
• Fully automatic PLC control: Touchscreen operation, remote communication ready. Your operator does not have to stand there and watch it.
• Precise concentration: Feed rate and water flow are tied together. Concentration stays within plus or minus 5 percent.
• Works with dry powder and emulsion: One unit handles both. Just change the settings.
• Easy maintenance: Everything you need to check or clean is right where you can reach it. No special tools required.

Summary

A polymer preparation unit is not just a mixing tank. It affects your chemical accuracy, polymer activation, operating costs, and finally your sludge dewatering performance.

A few rules of thumb for selection:

• Pick triple tank if you can. Skip double tank unless you have to.
• Pick stainless steel if your budget allows. Avoid plastic if you want it to last.
• Leave yourself 20% to 30% margin. Not too much, not too little.
• Make sure the feeding system has anti caking features.

• Higher automation saves you more money in the long run.

Do not make the mistake of buying cheap. A low quality unit will cost you more in wasted polymer, downtime, and operator hours than you saved on the purchase price.
