A turbid monumental pond of 6000m2 turned clear by active biological manipulation.
Exploitation result of leased out farm is negative. In 2008 a project started to reallocate the farm. May 2015 it came available due to a novel court case. Renovation will take till app. Q2 2018.
Around 2010, part time involvement became a almost full time project. Early 2015 a steward took over several tasks. Waterdokter.nl will eventually return to the basis, ‘a Saturday hobby-job’: tree climbing/pruning,  wood sawing, plant nursing etc. (See contact page for availability update.)

Ovivo water (Christ Holland), Tunisia.
Heineken constructs a new brewery near Tunis. Ovivo has constructed a Reverse Osmosis unit with remineralization. French speaking operators were trained how to operate this equipment. Training consisted of a theoretical part and a hands-on operations part with deliberately introduced alarms.


Pentair (Norit Process Technology), Istanbul
P1000785Istanbul has two municipal dump sites. Together they are the second biggest in the world. Rain water percolates through these sites and gets significantly polluted. Through drains on plastic sheeting, this water is collected and treated. Due to future stricter EG regulations existing installations on both locations are replaced by a Pentair leachate Membrane Bio Reactor (MBR). Total leachate flow is around 5000m3/day, which makes this the biggest leachate MBR project in the world (status2007).
From May till December 2007 Michael A. Doude van Troostwijk was Pentair’s Process Engineer & Site Manager, responsible for Commissioning, Start-up and daily Operations. He was continuously on site.

Royal Dutch Air Force
Chinook met bambi bucketAs a result of international missions, Health Care specialists of the Air Force have a growing need for added expertise on drinking water and waste water. To fulfill these needs, a special training manual and a 5 day training session regarding Operational Water Management was developed. Course deals with topics like: Specific Regulations, Base Water Knowledge, Water Treatment Technology, Water Production Tools and Daily Operation. Course consists of a theoretical part and a equipment training part under simulated field conditions.

sonedeCommissioning and start-up of a big RO drinking water production unit for Sonede, Tunisia’s drinking water company. Eleven years ago, Ovivo supplied three comparable lines. In contrast to other RO’s in Tunisia, this unit operates without any significant operational problems. Original membranes are still in operation!!
Propose Ovivo / Sonede how to optimize existing pre-treatment line- and PLC control.

Waterdokter.nl liaises between the commissioning and construction team and authorities regarding possible to be adapted permits and procedures for the testing and commissioning phase. Goal is to identify needs as early as possible. Contacts with future operator to fine tune procedures also take place. Because of Waterdokter.nl ‘s technical background, also technical questions will be dealt with.

Cientific Committee Loosdrecht Lakes
The Loosdrecht Lakes is a famous Dutch water sports and nature area. Through the years water quality has gone down significantly through an overdose of incoming nutrients.
The city council of Wijdemeren has installed a Scientific Committee to advise her on possible solutions.
Waterdokter.nl brings in hands-on expertise on system optimization e.g. regarding nutrient removal/prevention, plus experience in nature conservation.


Own Research: Effluent Coagulation Optimization
foto sw1 jar-testerDrinking water and process water is often produced from surface water. First step is often a coagulation process. Added chemicals improve settling / removal of suspended solids.
Waterdokter.nl studied several raw water sources in The Netherlands. Waterdokter .nl visited several drinking water companies. Major savings up to 75% in direct costs are realistic by expert process optimizations. It was seen that some current processes have been running for 20 years without any significant attempt for optimization, using latest process technology. In Waterdokter.nl´s opinion, these processes run just ok, but several can do much better, if properly optimized.
Results of this study were published in the Dutch Water sector’s magazine H2O. Waterdokter.nl has much experience in optimizing drinking water production processes. This implies more that just quick laboratory testing and introducing new chemicals. Looking for optimum process conditions takes time. Training personnel and optimized dosing control are key factors for long term success. Plant capacity increases of 25-50%, at a better water quality, are not unrealistic. As a result of the H2O publication & acquisition, several drinking water companies investigated and optimized their treatment.

Doude van Troostwijk is now a Technical Specialist. He will not be involved in military aspects of peace keeping missions. Instead Dutch Ministry of Defense can ask him to help local administrations to improve their water situation and thus increase humanitarian circumstances. Think of: short term, start-up and optimization of local civilian drinking- and waste water treatment facilities, long term, policy making & planning. Strengthen water policy Dutch Ministry of Defense.

It was adviced to break full grown hardness pellets coming out of the softening reactors and refeed them. This not only saves the normally used sand as crystallization ent, more important, it provides pellets with 100% CaCO3 in stead of a SiO2 core. Waternet is implementing it.
