Hamann VS Orca

Hamann by far

Noticed Microphor was not in the mix It seems for the last 6 months I have been in the (*^& at least once a week

Orca is by far the worst one! The Hamman system is very good, but requires that you pump your tank dry occasionally to rid the sludge.
The Headhunter Tidal Wave is also very good.

Personally if I had it my wave I would insist on an EVAC collection system and Hamann treatment with the discharge going through an electronic eye and substandard discharge returned to B.W. tank.

The tubulance in the tank generated by the EVAC pumps greatly reduces the sludge build up. but you still really have a look in there at least once a year

Hi,

I have had a number of systems over the years.

The simplest and most reliable was a holding tank and submersible pump, not treatment or electronics other than hi level alarm and no problems.

Now the the systems that offer to treat the goods.

ORCA- Without a doubt the worst piece of equipment to ever be installed onboard a boat.

MICROPHOR- Not as bad as ORCA but still need lots of TLC, Microphor toilets not cheap or very user friendly to repair the operating valves on either.

HAMMAN- The most reliable and user friendly units I have worked with to date, the Tank coating lasts like nothing I have ever seen before. I do not like the inspection hatch being mounted vertically as the stuff stuck to the lid tends to drip down the front of the machine as you open the tank. Holger Hamman agreed as a part of a long standing agreement with me to supply and fit a drip catcher under this lid and the level switches on the unit we have just installed. It hasn't been commissined yet but can only be an improvement to an already excellent design.

You guys really know your, er, stuff.

You tend to learn about these problems very quickly. I still have vivid nightmares about an Orca system blocked with a tampon, we were getting the crap kicked out of us in the Anagada Passage at the time, about 15 years ago. And I had drunk a bottle of Oringina about 1/2 an hour beforehand. Never touched the stuff since.

Hi,

K1W1,

I agree :
"The simplest and most reliable was a holding tank and submersible pump, not treatment or electronics other than hi level alarm and no problems."

I think this is the simplest

Hi,

I would have to agree a bit with that pic Garry but there is an even simpler system that I forgot to mention.

It has no pumps, no electronics, no pipes to block, only 1 moving part and it can save your life in an emergency.

It is the humble bucket.

Hence the depth of knowledge in dealing with $H1^

Just come across a product EM-1 which is a super microorganism for septic tanks. Anyone had experiance with this, I am thinking about using this in a Microphor system instead of Microphor supplied product.

Perhaps a bit off the primary topic but it's all sxxx anyway.
One insurance company that I'm aware of took note of the press on the high levels of cocaine "residual products" to be found in the Thames and Po rivers. Sampling has since been done on the blackwater treatment systems on a few offshore installations in the Gulf of Mexico and the North Sea. At least one nation's military sample the effluent on their naval vessels. I'm wondering if samples are being taken on yachts yet.

Haven't heard of sampling sewerage for drugs on yachts, however is becoming common practice for crew to have to submit regular urine samples as a condition of ongoing employment

Hi,

I don't recall seeing any offshore installations last time I was up the Thames maybe the authorities should look a little closer at what happens when it rains heavily in London. Invariably the Thames is flooded with tons of raw sewage. This is more likely where the Coke Residue comes from.

What do they propose to do try and isolate the DNA of the user from the residue and hope they get stopped in a traffic stop one day and swiped for a sample?

Gary is right random urine sampliong is becoming the norm in many contracts these days. I know of at least two yachts where the test kits are carried onboard for random testing whilst at sea and with guests onboard.

The offshore installation that was noted was a drilling platform. Positive result in the blackwater would trigger immediate sampling of all aboard.

I guess there is a good logic for that. I don't know how many people work on an oil rig at any one time but it would be a lot more than a yacht so I am sure it works out cheaper for the company to do it that way.
