On-site Visit to a Customer's Workshop | A Water Treatment Equipment Assembly Company 📷

Ahead of the Chinese New Year, Craier Water Treatment engineers and sales personnel visited customers' production workshops to observe firsthand how they assemble various components into complete water treatment systems.

Craier membrane housings undergo secondary processing before leaving the factory. The inner walls of the housings are inspected and trimmed to ensure they are free of burrs and scratches, thereby reducing potential damage to the reverse osmosis membranes during installation.

On-site membrane housing engineers also provided guidance on installation details and protective measures based on the customer's specific assembly methods, helping them to smoothly complete subsequent batch assembly.

Only by truly immersing ourselves in the field can we clearly understand the problems and find ways to further optimize the product.

Welcome to Craier water treatment equipment factory.

Today, let's quickly learn about our 1 ton/hour pure water system.

First, the process: stable and reliable.

The equipment adopts a mature "pretreatment + RO reverse osmosis + deep purification" process.

Raw water first passes through quartz sand and activated carbon to remove impurities and residual chlorine, protecting the core system;

Then it enters the RO reverse osmosis system, removing over 99% of salt, bacteria, and organic matter;

Stable production of pure water.

Second, the configuration details.

The main piping uses PN16 high-strength PVC pipe, which has high pressure resistance, long service life, and is leak-proof;

The reverse osmosis membrane housing is equipped with a sampling valve, which can individually monitor which reverse osmosis membrane is malfunctioning, and water quality can be tested at any time;

The control system supports manual/automatic/flushing modes, making operation and maintenance very convenient.

Suitable for multiple industries such as laboratories, electronic cleaning, pharmaceuticals, and boiler feedwater.

We focus on water treatment equipment, controlling the entire process from core components to complete machine assembly.

If you have any water needs, please feel free to contact us and we will customize a suitable solution for you.
