1、 Introduction to Electroplating Wastewater Treatment and Reuse Equipment

The electroplating wastewater treatment and reuse equipment consists of a reverse osmosis host and its pre-treatment and post-treatment parts. Using modern technology reverse osmosis principles, it removes organic matter, heavy metals, chemical compounds, and bacteria from the water with a removal rate of over 99%. The effluent meets the national wastewater standards.

In terms of electrical control and self-control, pressure automatic protection system and water quality automatic online monitoring instrument system are equipped, making the equipment control system clear at a glance. Wastewater is recycled through a wastewater recovery system, which can save over 75% of wastewater discharge costs. Using a reuse system can help enterprises achieve energy conservation and emission reduction, reduce wastewater discharge, and lower water costs.

2、 Scope of application of electroplating wastewater treatment and reuse equipment

The wastewater generated for all purposes in the electroplating industry is as follows:

1. Plating cleaning water

2. Waste electroplating solution

3. Flush the workshop floor, wash the electrode plates with water, condensate water from ventilation equipment, as well as various tank liquids and drainage caused by plating tank leakage or improper operation management resulting in "running, emitting, dripping, and leaking"

4. Equipment cooling water.

5. Heavy metal wastewater such as chromium, cadmium, nickel, copper, zinc, gold, silver and other heavy metal ions and cyanide

3、 Characteristics of Electroplating Wastewater Treatment and Reuse Equipment

The use of electroplating wastewater treatment and reuse equipment can not only effectively save limited water resources, thereby reducing water consumption and alleviating the increasingly prominent water shortage contradiction, but also reduce sewage discharge, reduce pollution to surrounding water bodies, and improve human living environment. The cost of enterprise wastewater recovery can be reduced to about 2 yuan per ton. Recycled water can be supplied to pure water systems or directly reused on production lines. It has good economic benefits and can recover initial design costs within 1-3 years. Featuring the following features:

1. Reusing wastewater and reducing the amount of rinsing water can further meet the zero discharge requirements for wastewater treatment, reduce the scale of biochemical and physicochemical treatment, and facilitate the expansion of enterprise production needs;

2. Recyclable useful metal ions, enabling enterprises to achieve environmental goals while generating benefits;

3. The effluent quality of the membrane is good, transparent, and higher than the process water requirements of the electroplating industry;

4. Short investment payback period and low risk;

5. Can be designed according to processing requirements, and continuously expand to increase processing capacity and improve processing capacity through continuous optimization;

6. Convenient system operation and small footprint

The use of electroplating wastewater treatment and reuse equipment to treat electroplating wastewater can meet the following wastewater discharge standards:

The first, second, and third level discharge standards of the Comprehensive Wastewater Discharge Standard GB8978-1996.

"Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002)

Guangdong Provincial Local Standard "Emission Limits for Water Pollutants" (DB44/26-2001)

4、 Notes and Case Analysis on Purchasing Electroplating Wastewater Treatment and Reuse Equipment

1. Suppliers can be requested to provide successful cases or go to the site to observe the results

To witness the effect and performance of the presentation on site, one needs to see it firsthand. I need to go to the site to see the effect of sewage treatment.

Speaking with facts, no matter how the supplier who provides you with the equipment introduces the superior performance of the equipment, you should ask the supplier to provide previous successful cases and then send someone to inspect the on-site sewage treatment effect. Although it may delay some time, it is crucial to test the professionalism of the merchants you cooperate with and whether the follow-up services can be provided in a timely manner.

There are many cases, serving Fortune Global 500 companies, military, government agencies, schools, and more, serving regions throughout the country,

If you need equipment for electroplating wastewater treatment and reuse, please feel free to inquire or visit the factory to see engineering cases. We are always ready to arrange for you and provide you with satisfactory results.

The following is a case study analysis: A customer (an electroplating factory in Shenzhen) discharged 50m3 of rinsing water for electroplating (nickel plating process) daily, with a nickel ion content of 200ppm, and treated with membrane method. (For reference only)

Daily treated wastewater volume: 50T/D, nickel ion content: 200mg/l;

Daily reuse water volume: 47T/D Reuse water conductivity:< 100us;

Equipment investment: 350000 yuan

Investment benefit analysis:

1. Recycling metal value: 50 * 0.2 * 300 * 50%=1500 yuan/day (metal nickel is calculated at the current market price of 300 yuan/kg, and the recycling price is calculated at 50%)

2. Reuse water value: 47 * 2.5=117.5 yuan/day (local water price in Shenzhen is 2.5 yuan/m3)

3. Reduce water treatment costs: 47 * 5=235 yuan/day (fees charged for discharge to the centralized control area or wastewater treatment dosing fees)

4. Daily processing cost: 400 yuan/day (including electricity bills, membrane replacement costs, membrane cleaning costs, etc.)

Daily investment return: 1+2+3-4=1500+117.5+235-400=1452.5 yuan/day

Investment payback period: 350000/1452.5/330=0.73 years (approximately 9 months)

2. Agreed effluent execution standards

Many customers who purchase electroplating wastewater treatment and reuse equipment do not specify the standard for wastewater treatment in the contract, which may lead to disputes if environmental protection requirements are raised in the later stage. Agree on the specific water quality of the effluent to avoid disputes. The cost varies depending on the process flow.
