Chemical Processing, Filtration & Dosing Pumps

Chemical processing is the process of altering the chemical structure of raw (bulk) materials to produce products applicable to other industries or in everyday life. Agrochemicals, petrochemicals, oleochemicals, ceramics, polymers, rubber, perfumes, flavours, and explosives are among these goods. Dowdens Pumping & Water Treatment supplies, installs and maintains various products, including pumps, piping, water and waste treatment systems used in chemical processing and filtering applications.

Chemical Processing, Filtration & Dosing Applications

Chemical processing, from ethylene and styrene to ammonia and butadiene, needs a thorough water and wastewater treatment process to guarantee high-quality, safe, and compliant operations. Dowden’s chemical treatment systems satisfy these operating requirements and assist in developing low-impact, resourceful plants that achieve longer run durations, encounter less fouling, and simplify operations and maintenance.

You make more money if you generate more products. Dowdens aims to help you achieve this through a customised water and wastewater treatment programme that boosts production. Our chemical treatments, which focus on quality and safety, are available for fouling prevention, corrosion and scale protection, antifoaming, and much more.

Common Industries Supplied

  • Accommodation & resorts: Bore water pumps and wells are essential to the effective and continuous running of accommodation and resorts. The importance of creating sustainable and cost-effective solutions for water delivery and maintenance cannot be understated in the industry. By creating a reliable source of water management, bore pumps and wells help the industry grow and operate without significant pain points.
  • Agriculture: Bore pumps and wells help farmers irrigate their crops more effectively, leading to higher yields and lower costs. They also provide a reliable source of water for other uses on the farm, such as washing livestock or watering gardens.
  • Aquaculture: Borehole pumps and wells are important to the aquaculture industry because they provide a consistent and reliable water supply for fish and other aquatic creatures. Without a stable and plentiful water source, the aquaculture industry couldn’t operate effectively. Bore pumps and wells also help regulate the water’s temperature, which is vital for the health of the fish.
  • Government: Few industries rely on consistent and efficient water pumps and wells more than the government sector. Sustainable water sources are an absolute necessity, so we have made it our business to help with water delivery, maintenance and management in countless areas — gardens and sporting fields, parks, buildings, etc.
  • Mining, oil & gas: Without wells and pumps, it would be much more challenging to extract the resources we rely on from the ground. Wells and pumps play an essential role in the mining, oil and gas industry and help us access the resources we need sustainably.
  • Residential: Bore pumps and wells provide a reliable, consistent water source for homes and businesses. They are also relatively affordable and easy to install, making them a popular choice for many homeowners.
