Case study - Tin plating wastewater treatment
The Client The Client is a steel industry based in the Middle East producing tinplates for food cans. Tinplates provide excellent corrosion resistance and are produced starting from cast iron by several steps. Cast iron is first rolled to get thickness in the range of 0.2 – 0.3 mm than it is electroplated from aqueous acid solutions at a temperature around 60°C. The plating bath contains iron sulphate, phenol sulfonic acid and tin salts, as in the table. At the end of the process plating thickness is...

Treating pharmaceutical wastewater - Case Study
A pharmaceutical facility in the Caribbean had an existing wastewater treatment process that utilized a sequencing batch reactor (SBR). SBRs use large tanks to collect wastewater, then a number of different options can be employed to treat the water (such as chemicals addition, aeration and mixing). When an SBR aerobically breaks waste down, it can produce a high volume of air that needs to be treated before discharged into the atmosphere. Large catalytic oxidation (CATOX) units are often used to treat the off...
Treatment of Cyanide Bearing Wastewaters
Water Innovations utilizes a 2-stage Cyanide Oxidation (CN) system that can treat from 2 GPM to 10 GPM. In the first stage of treatment, hypochlorite oxidizes cyanide to cyanate. It consists of two double-wall “Batch” Cyanide Oxidation Tank and an accumulation tank for cyanide-bearing rinse water, each tank equipped with one mixer. Wastewater containing cyanide will be pumped or flow by gravity into the first tank and then on to the second tank for complete cyanide oxidation. Both tanks have liquid...
What is a wastewater treatment system and how does it work?
For industrial companies producing wastewater as part of it’s process, some type of wastewater treatment system is usually necessary to ensure safety precautions and discharge regulations are met. The most appropriate wastewater treatment system will help the facility avoidharming the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It will also help the facility curb heavy fines and possible legal action if wastewater is being improperly...
