Vodaflo Ltd. is a company specialized on water treatment. We offer with our partners a wide range of products to our clients. Vodaflo was established in 2013 and the key personnel have experience on water treatment for over ten years. Projects related to water treatment issues and challenging microbiological problems have been executed in Finland, Russia,  Brazil, South Africa, Saudi Arabia, East Timor and on the cruise liners at Mediterranean and Atlantic. Vodaflo is also specialized in training of WWTP operators and offers a training platform. The deep knowledge of peroxides has been acquired by research and training. Peroxides combined with clever automation provide cost effective treatment solutions.

Finntreat Oy is a process and project management adviser company founded 1982. FTOY has since then worked in KSA in various STP projects including Jubail Industrial City STP Phase 1 and WWTP Phase 1, Arana 1 of Makkah and Khumrah 4 of Jeddah. In Vietnam FTOY was involved in Hanoi water project. In EAR FTOY was advisor in Beni Suef Governorate water and wastewater project. In Finland FTOY has been involved in tens of STP and WWTP projects.

PAA-System utilization in Primary treatment The primary treatment consisting of inlet PS, screening, grit and grease removal and primary clarification causes odor, corrosion and occupational health problems by H2S in all STP due to warm septic influent. PAA-System is used by dosing PAA to influent at PS or into nearest manhole to mitigate the problems. The process control developed by Vodaflo ensures the elimination of H2S in all the primary treatment unit operations and controls the dose to those, only. Sludge treatment using PAA-System PAA-System is used to control H2S in especially anaerobically digested sludge to eliminate odor, corrosion and occupational health problems in effective way. The H2S is oxdiced to S and the anaerobic bacteria producing hydrogen sulphide eliminated. This is why there is not any more H2S in gaseous phase causing the problems. The pilot run at Manfouha STP proved the process to work in excellent way. The process helps in smelly partially aerobically stabilized sludge, too. Replacement of chlorine in disinfection Chlorine is an old disinfection chemical for effluent. Anyway it causes harmful bi-products especially in treated sewage effluent disinfection. And as an old chemical warfare agent chlorine is dangerous if ending in wrong hands. Tens of ton containers are stored in STPs close to or even inside the cities. Tests were conducted at Manfouha STP to prove the feasibility of using PAA in disinfection of effluents of N/E and S plants. Other disinfection methods UV and O3 are effective but act at the spot of treatment as the effect is not available outside UV unit and due to the instant reaction rate of ozone. PAA has been used for effluent disinfection in Finland during several years. A globally common strategy is to replace chlorine in disinfection of effluents that is in plans of NWC of KSA, too.   Vodaflo – peroxide system

General Description:

Vodaflo peroxide system is an automated system for water quality measurements and chemical feeding. Combined with latest industrial automation and network connection the system can be remotely controlled and online data stored to a cloud service. The peroxide system can be used to a wide variety of applications from disinfection to toxic gas removal. The system is suitable for potable and waste water processes and is easy and fast to apply to a working process. Only a small footprint is needed. Equipment can be delivered as a skid mount, separate units or for outside use in an isolated container.

Applicable to: 

A new or a working process Potable and waste water treatment processes     Pipelines and open channels Pressurized system

Qualities:

Toxic gas removal

• Effective against sulfur and nitrogen compounds
• Reduces bacteria which produces sulfur and nitrogen compounds
• Prevents anaerobic states
• A safe working environment – H2S is a deadly gas
• Vodaflo peroxide system not only removes H2S but prevents it from forming  Corrosion removal
• Combined corrosion speed reduces
• Corrosion in pipelines is usually from microbes called as biocorrosion (Microbially Influenced Corrosion, MIB)
• Removes biofilm and prevents new growth  Disinfection
• Effective on Legionella and other difficultly removable bacteria
• Effective on coliphages  Automated feeding
• To minimize the chemical consumption
• Based on applicable measurements such as flow, ORP, H2S, sulfide, turbidity, Suspended solids
