About Us

Zülal Su Teknolojileri was born in 1998 from a small filter workshop set up in Gebze by two chemical engineers. In the early years we made inlet filters that removed iron and manganese from well water. Today we bring the same experience to reverse osmosis, ultrafiltration, ion exchange and biological treatment technologies.

Manufacturing strength

At our 12,000 m² plant in the Gebze Organised Industrial Zone we produce home units, pressure vessel filters, membrane housings, control panels and automation systems, and packaged wastewater treatment units. About 80% of production is our own design, which shortens service times and spare-part access.

Our people

The team consists of 34 engineers (environmental, chemical, mechanical, automation), 120 service technicians and nine analysts working in our accredited laboratory. For after-sales support there are 36 service points across Turkey.

Our values

• Honest advice: we do not sell capacity you do not need; we size to the analysis result.
• Low operating cost: we design systems with low energy and chemical consumption.
• Sustainability: water reuse, cutting plastic bottle consumption and low energy use are priorities.
• Long life: we guarantee spare parts for ten years.

Our head office and factory are in Gebze; regional offices are in Ankara, Izmir and Antalya.
