Water & Wastewater treatment
Throughout the past century, environmental experts have been working together to find ways to combat significant industrial and societal water-related challenges and have found solutions to help tackle them. Safe, sustainable chemicals that are as eco-friendly as possible are essential in helping to sustain the current drinking water and wastewater treatment levels, playing a crucial role in our daily lives. This is where WTW (water treatment works) and WWTP (wastewater treatment plants) come into play. Water treatment is the name given to any process that removes contaminants to make it suitable for specific end-uses, like drinking. WTW transforms raw water into drinking water for human consumption and for producing food, pharmaceuticals, and other essential products.
In comparison, WWTP removes pollutants, parasites, viruses, and chemicals from wastewater before releasing it into a body of water to prevent further pollution and detrimental environmental consequences. Water becomes wastewater when there are changes to its composition or quality and is divided into two categories, sewage water and industrial wastewater. Sewage water comes from domestic dwellings such as toilets, sinks, and showers, and industrial wastewater, which originates from medical, domestic, commercial, agricultural, and transport activities.
Trantec and the water sector
Trantec’s equipment offers several benefits in the water sector. Our bespoke, fit-for-purpose equipment to meter, dose, and convey dry bulk solids into water treatment and wastewater processes is designed to enhance efficiency and accuracy. From screw feeders to flexible conveyors and sack tip stations to bulk bag dischargers, our equipment is known for its 100% functionality and trouble-free integration into your existing system, saving you time and resources.
Trantec engineers hold a lifetime’s worth of experience in the design and manufacturing of material-handling equipment and have extensive knowledge surrounding material variants, properties, and characteristics, giving us the edge in producing specialist equipment suited to all kinds of applications. The dedication, time, and research committed to making our equipment is reflected in our products, which boast a superior build and unmatchable quality. Consequently, Trantec equipment is known worldwide and deployed globally, not only in the water sector but in the plastic, pharmaceutical, chemical, and food industries, to handle materials in pellet, powder, gain, granular, and flake forms.
We offer a wide range of volumetric, gravimetric, and micro screw feeders, suitable for both free-flowing and non-free-flowing chemicals. Our feeders come in various finishes, from weld-as-laid to crevice-free, to meet a broad spectrum of dosing needs. Customisable features are available to enhance functionality, including quick-release mechanisms for rapid dismantling, easy-to-clean components suitable for autoclaving, and mobile packages for easy manoeuvrability.
Recently we supplied several pieces of equipment to one of our clients in the water sector, which included volumetric screw feeders and multiple flexible screw conveyors for handling and dosing powder-activated carbon. Activated carbon is frequently used in water treatment due to its highly absorbent, large porous area, which adsorbs natural and organic compounds, odour and taste compounds, and synthetic organic chemicals.
Examples of solids typically dosed within the water treatment sector:
- Granular Activated Carbon (GAC)
- Sodium hydroxide (pH correcting)
- Magnesium oxide
- Ion exchange resin
- Barium carbonate
- Dye powders
- Pulverised fly ash
- Hydrated Lime
- Powdered or granular chemicals
- Dry polymer
- Clay feed
- Anthracite
- Sodium bicarbonate (pH correcting)
In addition to our extensive range of metering screw feeders, Trantec frequently deploys FIBC dischargers and sack tip stations in conjunction with flexible screw conveyor systems to efficiently unload and transport chemicals into water and wastewater treatment processes. Our equipment offers optional features to minimise downtime and enhance safety and hygiene.
Screw Feeders – Versatile in configurations, allowing for various feed rates and handling of various material types. For food and pharmaceutical application our feeders can be equipped with a quick release mechanism to facilitate easy and fast removal and reattachment of components.
Flexible Screw Conveyors – Our conveyors come equipped with quick-release safety switches on the clamp flanges and motor adapter, allowing for the safe and rapid removal of the tube and spiral. This feature helps in maintaining safety and efficiency during maintenance.
FIBC Dischargers – These units can be connected to a dust collection system to manage airborne chemicals or feature integrated screens to contain dust. Our equipment is designed to be adaptable, with options such as an adjustable heightened frame design to accommodate various bulk bag sizes and types, ensuring it meets your specific needs. For low-headroom spaces, we also offer split-frame dischargers.
Sack Tip Stations –We can equip our stack tip stations with interlocking swivel wheels (caster package), an empty sack disposal spigot, a filtration system, and a dust extraction spigot. Additionally, we provide interlocking safety doors and switches to ensure a safe, dust-free unloading process.

Flue Gas Desulfurization
Flue gas desulphurisation (FGD) involves removing sulfur dioxide (SO₂) from the exhaust flue gases of fossil-fuel power plants and other industrial processes. Several bulk solids are used in FGD processes to neutralise and remove SO₂. Some of the key materials used include Fly ash, Limestone, Hydrated lime, Magnesium oxide, Activated carbon, and Sodium bicarbonate.
Trantec SOLUTIONS
Flue gas scrubbing applications require conveying and feeding equipment to safely and efficiently transport and dose powders and other types of chemicals into a Flue gas treatment process. At Trantec, we specialise in manufacturing a range of equipment capable of precisely dosing material in large quantities down to fractions of a gram per hour.
Trantec manufactures a Reagent Cabinet equipped with a gravimetric screw feeder for precise dosing of bulk materials in powder, granular and grain forms. Our Reagent Cabinet was developed after being approached by a Europe-based cremator and incineration equipment manufacturer. Their application involved dosing activated charcoal as part of a cremator incineration process.
Taking on the challenge, Trantec designed a system that ensured accurate and efficient dosing and handling of bulk materials. By integrating a load transducer weighing base using four load cells, the reagent cabinet was to be operated using continuous loss-in-weight configurations. Our client’s pre-existing control systems control it, although Trantec can supply PLC-based controls for any Gravimetric Feeder.
